Been TTC for 2 years now and AF arrived today so absolutely gutted. Seen three doctors in the last year who don't feel there is anything to worry about (one even said I will be pregnant before he 2 year mark!) DH has had a semen sample done (all normal) and I have had two blood tests for thyroid and progesterone and all normal. I think because DH and I are slim, fit and healthy, don't smoke or drink, the docs don't feel the need to do any more tests. I'm booking another appointment to push for scans but wondered if there were any positive stories of folks who conceived naturally after trying for more than 2 years? Otherwise it looks like it will be the IVF route for us.
